Throttle bodies
 

My throttle body is a bit suspect at the moment.
Ordered a replacement and when it arrived it didn't fit.
Closer inspection revealed that the replacement had a bolted body and 2 plug sockets whereas mine has a riveted body and a single, 6 pin plug socket.
Anybody know why the difference?

the two plug ones are on earlier cars and the single plug on latter cars( post 2006)

they both send the same signals to the ecu just a cost reduction to use a single plug rather than two

That's fine except mine is a 2004!

The bolted body is most likely for 2002 to 2004.25 model year X-Type. Prior to April 2004 the x-types electrical systems are all the same. After April 2004 Jaguar did a major renovation of the x-type electrical system and that would account for the changes in the plugs on the throttle body. The new one is for the late 2004 and up.

Thanks guys.
I'm guessing that the TPS is fully integrated on the later one, hence the single socket.

It is, yes.

Ordered the correct replacement and the car immediately started behaving itself.
It hasn't even arrived yet.
I won't mention the rust that has suddenly appeared around the left rear jacking point.

Oh shit! Pull the rocker plates immediately!! There are horror stories in this forum of rusted out support beams under there. I have a thread on how to rust protect your car, just search my name.

Thanks Dell, I saw the post previously.
Work is looming and I haven't got time to investigate further.
Still trying to sort horrible camber on the rear wheels that wore down a pair of tyres in no time at all.
And figure out what the worsening squeaking on the XJR-s is.
And figure out why the fuel gauge on the Freelander is showing full all the time.
Still, now that the weather has changed and gotten a lot cooler the a/c on the X Type seems to have been finally fixed so it's not all bad news.

Do the "Thermo" fix for your rear camber. I was going to do it on mine, got under doing something else and mine already had them.

What was the Thermo fix again?
I've ordered replacement (Volvo) upper control arms, even though there is no apparent wear in the bushes on mine anyway.
Also figured out the oval washer adjusters on the transverse beam; just need to find some proper camber figures from somewhere.

Here are the figures on my alignment done after replacing front components and the front lower rear arms on mine.

Thanks Dell.
There must be some camber adjustment on the oval washers as per the picture?

Idk, bear in mind my mentioning my car has the "Thermo'd" upper control arms thus my rear alignment being spot on.

Thanks for that.
Is that an old photo or is it just the angle because it looks like a nasty crack spreading from the bottom of the control arm bracket?

Well, damn, never noticed that. Guess I'll be running it out soon to H.A.F.B. shop to put it on the rack and look at that!!

Steve M: Those oval cam bolts on the rear cross member are for adjusting rear toe-in / toe-out.

The only way to adjust rear camber is with Thermo's adjustable upper control arms.
